Is this trial a fit for you?

Likely a good fit

Adults 18–60 with active RA (DAS28 > 2.6) on methotrexate and standard therapy who can provide informed consent.

Probably not a fit

Individuals not showing an inflammatory response or with safety concerns may not experience benefit from add-on desloratadine.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, double-blind, placebo-controlled trial will add desloratadine 5 mg daily to participants' usual DMARD regimen for 12 weeks to see if it lowers RA activity and inflammatory markers. Participants with active RA (DAS28 > 2.6), aged 18–60, on methotrexate, will be assigned to desloratadine or placebo in parallel groups. Outcomes will include disease activity scores, inflammatory biomarkers, and patient-reported measures, with safety monitored throughout. If desloratadine shows benefit and tolerability, it could support a novel adjunctive approach for RA management. The study leverages prior evidence of anti-inflammatory effects beyond antihistamine action, explored in a controlled RA population.

Why it matters

Potential benefit: If successful, desloratadine could become a safe add-on option to improve symptoms and inflammation in RA patients on standard therapy.

How similar studies have gone: Prior work suggests anti-inflammatory properties of desloratadine, but robust RA-specific evidence from randomized trials remains limited.
